Hyaluronic acid, also briefly referred to as hyaluron, is a basic structural component of the skin. Our body synthesizes hyaluronic acid itself, and at least 50% of it accumulates in the skin. Its role is to maintain the natural smoothness and humidity of the skin.
As aging advances, hyaluron decreases
As the age grows, the amount of hyaluron in the skin progressively decreases, along with the collagen and elastin skin proteins. This is why, over the years, our skin loses its elasticity, relaxes and dries. Wrinkles start to appear.
A new study, published in the Journal of Clinical, Cosmetic and Investigational Dermatology, shows that the use of hyaluronic acid, orally or locally acting on the skin, is an effective mean of reducing wrinkles.
The positive effect comes from the enormous water retention capacity of hyaluronic acid. It can absorb water in a quantity several times greater than its own.
Protects skin barrier
In addition to moisturizing the skin and smoothing wrinkles, this effect of hyaluronic acid also helps to maintain the barrier function of the skin, which is directly dependent on maintaining the balance of water and lipids in the epidermis.
Case study in Japan
The study was conducted in Japan and covered 60 men and women aged between 22 and 59 years. For 12 weeks, they received 120 mg of hyaluronic acid. After this period a three-dimensional skin analysis was performed to monitor the effect.
It has been found that compensating for loss of hyaluronic acid with age through its additional intake restores the natural water lipid balance of the skin, its smoothness and elasticity.
The effect is most noticeable in the areas where wrinkles are formed, even the finest of them, in the areas around the eyes and lips, visibly smooth out. Within the 12-week hyaluronic acid dose, about 50% reduction in skin wrinkles is reported for both sexes.
The conclusion of the Japanese research team that carried out the study is that hyaluronic acid can be used to maintain good appearance and skin health on a long-term basis.
Its regular intake, especially after 30 years of age, can effectively protect the skin from the negative environmental factors that drain it and increase the risk of wrinkles.
